Although CNC
Parts are far better due to an accurate machining process, CNC aluminium parts
pose a problem during the manufacturing process. The most prominent problem
faced during CNC machining of Aluminium parts is overheating, which cases the
part to deform and sometimes melt. This happens because not all Aluminium
alloys are suitable for machining, also selecting an appropriate feed rate and
tool is extremely important for creating CNC aluminium parts. Only an
experienced CNC operator can work on aluminium parts and select appropriate
cutting parameters in order to ensure the best results. At HG Precision, all
our employees are trained to create custom machined parts according to your
needs. In addition to selecting the appropriate parameters, there are several
other techniques that can improve the results, some of them are as follows:
With
this technique, heat is distributed more evenly across the work piece resulting
in better heat dissipation. With this technique, we can avoid heat
concentration on the part which would ultimately reduce deformation of the
machined part.
In
this method, cavities in the work piece are dealt with at the same time, making
it harder for the uneven forces to deform the part. With the application of
uniform force, stress concentrations in the part will be reduced which would
increase the lifecycle of the part.
It is
obvious that the properties of the cutting tool would play an important role in
the machining process. The combination of the geometric and material properties
of the cutting tool allows us to control the applied force and heat dissipation
on the part. By changing the front angle, rear angle, helix angle and the main
deflection angle, we can change the force applied on the part and the average
temperature of the processing area.
As
described above, the cutting tool is quite important for the machining process,
so it must be properly cared for. With regular inspection of the cutting tool
and proper maintenance, the results can be significantly improved.
Not all alloys of
Aluminium are suited for precision machining process, though their performance
can be increased by applying the above-mentioned techniques, it is better to
select an alloy with mechanical properties suited for this process. Aluminium
grades such as 6061, 7075, 2024, 5052, and 6063 are some of the popular choices
for CNC aluminium parts.
